Transurethral Bipolar Enucleation of the Prostate Is an Effective Treatment Option for Men With Urinary Retention

Risk factors for the postoperative bladder neck contracture in patients with small-volume prostatic hyperplasia

OBJECTIVE

This study was to explore the risk factors for postoperative bladder neck contracture (BNC) after transurethral operation of prostate in patients with small-volume prostatic obstruction.

METHODS

Clinicopathologic data at our center from February 2016 to January 2020 were retrospectively collected and analyzed. Clinicopathological characteristics between patients with and without BNC were compared. Multivariate logistic regression was used to determine the risk factors for postoperative BNC.

RESULTS

There were a total of 39 patients (8.53%) with postoperative BNC. Multivariate logistic regression analysis demonstrated that preoperative bladder neck diameter (BND), intravesical prostatic protrusion (IPP), surgical methods (transurethral resection of prostate (TURP)/anatomical endoscopic enucleation of the prostate (AEEP)), and postoperative urinary tract infection (UTI) were independent risk factors for postoperative BNC in patients with small-volume prostatic obstruction (P < 0.05). The incidence of postoperative BNC in patients undergoing AEEP was significantly decreased compared with those undergoing TURP. The optimal cut-off value of preoperative IPP was 6.10 mm while the optimal cut-off value of preoperative BND was 2.52 cm.

CONCLUSIONS

Larger preoperative bladder neck and higher preoperative IPP lead to decreased incidence of postoperative BNC in patients with small-volume prostatic obstruction. Active management of postoperative UTI could effectively prevent the occurrence of postoperative BNC. Compared with TURP, complete AEEP would contribute to reduce BNC in patients with small-volume prostatic obstruction.

Influence of transurethral enucleation with bipolar of the prostate on erectile function: Prospective analysis of 51 patients at 12-month follow-up

Background

Transurethral enucleation with bipolar (TUEB) is a safe and effective surgery for benign prostatic obstruction (BPO). However, few data exist concerning the influence of TUEB on erectile function (EF) in patients with BPO.

Objective

To evaluate the influence of TUEB on EF in patients with BPO at 3- and 12-month follow-up.

Material and methods

We prospectively enrolled 51 patients who underwent TUEB from June 2016 to April 2020. We evaluated maximum urinary flow rate (Qmax), postvoid residual urine (PVR), International Prostate Symptom Score (IPSS), quality of life (QoL), and International Index of Erectile Function-5 (IIEF-5) preoperatively and at 3- and 12-month follow-up. We classified the patients according to their preoperative IIEF-5 score into group 1 (IIEF-5 ≥10; n = 24) and group 2 (IIEF-5 <10; n = 27), and for further evaluation of EF, into subgroups a: severe (IIEF-5 5–7), b: moderate (8–11), c: mild to moderate (12–16), d: mild (17–21), and e: no erectile dysfunction (22–25). Data are displayed as median or median (interquartile range).

Results

The study comprised 51 patients with a median age of 75 (70.5–79.5) years. Median prostate and transition zone volumes were 69.5 (46.5–78.8) mL and 30.5 (19–43) mL, respectively. Urinary function improved significantly when comparing respective preoperative, 3-month, and 12-month follow-up values: Qmax (7.6, 12.9, 15.2 mL/s), PVR (50, 0, 0 mL), IPSS (20.5, 9, 6), and QoL (5, 2, 2), respectively. There was no significant change in IIEF-5 score across the three time points: 9, 7, 8. The IIEF-5 score slightly but significantly increased between the preoperative and 12-month follow-up values in group 2 (5, 5, 6) and subgroup a (5, 5, 5).

Conclusion

TUEB was effective and safe surgery for patients with BPO and showed no significant influence on EF at 12-month follow-up after TUEB in patients with BPO.

Differences in surgical and functional outcomes in benign prostate hyperplasia patients with only lower urinary tract symptoms versus those in retention: A systematic review and meta-analysis

AIMS

To evaluate outcomes after benign prostate hyperplasia (BPH) surgery among men with lower urinary tract symptoms (LUTS) only versus those with urinary retention (UR).

METHODS

The protocol was registered in PROSPERO with ID#232253. Eligible studies identified from four electronic databases. Search, data extraction and quality assessment were performed independently by two reviewers. Studies with perioperative, functional, early and late complication outcomes included.

RESULTS

Twenty-five studies, 14 593 patients including 1 randomized controlled trial, 11 prospective and 13 retrospective studies included for meta-analysis. This showed higher risk of immediate transient recatherization (risk ratio [RR]: 5.29, p < 0.00001), longer days to trial-off-catheter (mean difference [MD]: 0.25, p < 0.00001), longer hospitalization stay in the UR group (MD: 0.35, p < 0.00001), and higher risk of intraoperative blood transfusions (RR: 1.90, p = 0.002), postoperative urinary tract infections (RR: 1.49, p < 0.00001) and sepsis (RR: 8.15, p = 0.009) too. Failure of surgery like permanent recatheterization (RR: 5.27, p < 0.00001) was more in preoperative UR group. Negligible differences seen in long term functional outcomes between the two groups (International Prostate Symptom Score at 12 months, MD: -0.06, p = 0.68; Quality of Life at 12 months, MD: 0.20, p < 0.00001; maximum urinary flow rate at 12 months, MD: -0.33, p = 0.10; and postvoid residual volume at 12 months, MD: 4.32, p < 0.00001).

CONCLUSIONS

Preoperative UR patients undergoing surgery for BPH have higher risk of postoperative complications versus LUTS only group including the need for permanent catheterization. Both groups had similar long-term functional outcomes. We could infer that patients with UR on whom surgery is successful, with time may recover bladder function akin to patients with LUTS alone.

MODERN METHODS OF ENDOSCOPIC ENUCLEATION OF BENIGN PROSTATIC HYPERPLASIA AND PROSPECTS FOR THEIR MODIFICATION

The disadvantage of bipolar and holmium enucleation in transurethral surgery of benign prostatic hyperplasia (BPH) is the frequent postoperative urination disorders. To increase the effectiveness of surgical treatment, a modification of the surgical technique is necessary.Objective: to compare the perioperative results of endosurgical treatment of large sized BPH using transurethral bipolar (TUEB), laser (HoLEP) and modified laser prostate enucleation (HoLEP-M) methods. Patients and methods: A randomized prospective study was conducted according to the results of surgical treatment of 1104 patients with BPH with a volume of 80 to 350 cm3, divided by methods of endoscopic enucleation of the prostate. A mod-ification of the HoLEP technique was to optimize access to the surgical site with the designation of new anatomical landmarks.Results: Comparison of surgical methods showed their equivalence in the volume of removed tissue, the low frequency of hemorrhagic and infectious complications, the dynamics of urological indicators in the delayed period. TUEB has the least parameters for the time of surgical intervention (98.2 ± 2.24 min.), the vol-ume of blood loss (65.5 ± 1.83 ml), the terms of postoperative catheterization of the bladder (2.0 ± 0.32 days), and the days of hospitalization (3.2 ± 0.40 days). The safety of laser methods is higher than TUEB, during which 3.1% of closed perforations of the prostatic capsule and bladder were observed (versus 0.8-1.5% with laser methods). Modification of the HoLEP technique allows reducing the frequency of late dysuric disorders by 2-3 times, urinary incontinence by 3.4-4 times, cicatricial complications by 1.7-2 times.Conclusion: Bipolar and laser methods of transurethral enucleation of the prostate of large sizes are comparable by criteria of complete removal of prostatic tissue, effectiveness and tolerability in patients with thrombohemorrhagic risk. In terms of the frequency of intraoperative injuries, the safety of laser methods is higher due to the reduced penetrating ability of laser energy. Modification of surgical access to the prostate preserves the prostatic urethra as much as possible and is a promising measure for the prevention of late obstructive and functional complications of transurethral interventions.

Sexual outcomes of endoscopic enucleation of prostate

The emergence of various endoscopic enucleation techniques in the past decade has provided surgeons with more options and opportunities in performing enucleation. With the same surgical principle as holmium laser enucleation of prostate, the early results of different techniques were comparable. However, sexual outcomes of endoscopic enucleation of the prostate (EEP) were less commonly reported than the voiding and urodynamic outcomes. In this review, the sexual outcomes including erectile function, ejaculatory and orgasmic function of various endoscopic enucleation technique would be studied. The overall sexual outcomes were heterogeneous and inconclusive. Outcomes measurement, sample size calculation, hypothesis generation and selection criteria were not specifically designed for sexual outcomes or even available. There were also limitations in the individual sexual assessment tools. Nonetheless, most studies showed no significant deterioration of erectile function after EEP, and ejaculation dysfunction was common. Looking forward in the field of benign prostatic enlargement surgery, the 'one size fits all' notion should be abandoned. Treatment should be tailor-made according to the prostate size, co-morbidities and sexual needs. The sexual outcomes of enucleation have to be better studied and defined. More prospective controlled studies focusing primarily on sexual functions are needed. For enucleation surgeons, exploring different ejaculatory-sparing technique could be the golden opportunities in further consolidating the role and expanding the indication of enucleation surgery.
